Collapsible tube-type package for pastelike substances comprising a rigid container and an inner flexible bag

Abstract

A package comprising a rigid outer container and a flexible inner container. The closed end of the inner container is provided with a shaft. When empty, a length of the inner container is wound around the shaft from which it is arranged to be unwound as the inner container expands during filling.

What I claim is: 
     
       1. A package especially for pastelike substances comprising a rigid container having wall means which define an interior space and also define an opening, a filling and dispensing device secured in said opening and defining a passage extending between said interior space and the exterior of the container, a flexible bag of tubular form disposed in said interior space and having an open end which is secured to said filling and dispensing device whereby said passage establishes communication between the interior of the bag and the exterior of the container, said bag also having a closed end, and a roller which is rotatably mounted on said container close to the filling and dispensing device and is secured to the closed end of the bag, the bag being in a flattened condition and devoid of pastelike substance and a part of it forming windings around said roller whereby on filling the bag by way of said passage the bag may expand by unwinding from the roller to substantially fill said interior space, and wherein the container is formed with ears extending in said interior space and the roller is mounted on the container by being journalled in said ears. 
     
     
       2. A package as claimed in claim 1, wherein there are two ears, one at each end of the roller. 
     
     
       3.
